Specification of Letters Patent.

Patented May 1 1, 1 909.

Application filed April 6, 1908. Serial N0. 426,459.

To all whom it may concern:

Be it known that I, HIDALGO MOYA, a citi- 7161 of the United States of America, residing at leicester, En land, have invented certain new and usefu Im rovements in Type- VVriters of the Typea1 Class, of which the following is a specification.

This invention relates to improvements in type-writers of the ty e-bar class and the objects are to simplify t 1e construction of the key-lever mechanism and the operation of the type-bars thereby and to provide simple means for shifting the type-bar mechanism in relation to the platen by a shift-key and for swinging the whole key-lever and typebar system clear of the remainder of the machine or for separating them entirely.

According to this invention each of the type-bars (which are normally vertical) is combined with a floating key-lever constrained to move up and down and having an arm engaging the type-bar to tan-n the same and a spring is arranged to restore the typebar and key-lever to their normal positlons. The key-lever may be in the form of a floating bell-crank lever having an approximately vertical slot engaging a fixed rail; an arm of the key-lever engages a recess'in the type-bar near its pivot and a spring connects the typebar with thekey-lever and tends to maintain them in their normal positions. This arran gement is such that as the key-lever is depressed and the type-bar turns, the spring while bodily descending at the same time extends; and when the key-levcr is released the contraction of the spring raises both t e-bar and key-lever to their ,original positions. Each ty e-bar may have a cam-she ed end arrange to engage a universal bar w \ich 0perates the escapement of the platen carriage, so that the depression of each key-lever ef feels the desired travel: it is thus possible for the key-lever and type-bar mechanism to be entirely self-contained and separate-from the fixed base comprising the carriage and ribbon mechanism. The up or frame carrying the key-lever and typear system may be entirely detachable from the rest of the machine so that type sets for different languages may be substituted on thesame inavhine together with a key-board suitable. for the language. In a machine having two or more types on the one type-bar, the fraine carrying the key-lever and hype-bar mechan;

use by pivoted arms and a shift-key is arranged to move said frame into different positions in relation to the platen.

In the accompanying drawings which illustrate by way of example one form of typewriter embodying this invention Figure l is a central vertical section of the machine in normal position; Fig. 2 is a similar view show ing one ty c-bar and key-lever in depressed position; 3 is a plan of a machine; Fig. 4 1s a perspective View of the universal escapement bar and its supports; Fig. 5 is a part vertical section showing the arrangement of the slidin block on the fixed frame; Figs. 6,

7 and 8 il ustrate the shape of the key-levers of the first, second and third rows respectivcly. Figs. 9 and 10 are elevation and plan illustrating a modified arrangement of space bar; 'Fig. 11 is a side view showing the operation of the'shift hey.

Like letters indicate like parts throughout the drawings. I

On a fixed base A is mounted any suitable well known form of platen carriage having the usual platen or impression roller B, the appurtenances of which form no part of this invention and are not illustrated in detail.

An upper frame C is mounted on the base A and the connection between them will be described hereinafter. Thelower and main part of the frame C is an arc-shaped block on which the ty e-bar and key-lever mechanism is carried. tical rods C carrying a cover C" for the t pc, and a ad 0 against which the type ars normally lie. Each type bar D is pivoted at D in the frame C and in the arrangement illustrated carries three t po s (Z d (i On the front of the frame C is mounted a fixed rail E to SGIXG as a uide for the key-levers F. Each key-lever F w s the usual hey F and has an arm F terminating in a rounded end which engages with a recess U" in the type bar D close to the ivot D. An a proximately vertical slot is formed in t (2 keylvvers and engages the fixed rail E. V A spring (i connects theup or part ofi thc key-lever F with a point on, is ie type-bar D so that the arm F engages. the type-bar between the pivot D and the point of application of the spring. The spring G is-in tensionand it tends thereforeto maintain the key-lever F andthe type-bar D in the position inwhich thasprin is contracted, that is the normal PPSit oni ustratod in Fig. 1.

When thakcy fill t the ends of this block are ver F is depressed the low nd of the arm F moves around "the pivotl) through a quarter of a turn and the key-lever as a whole moves bodily down and is guided by the engagement of the rail E with the slot F. Durin this depression the spring G is extended as s own in Fig. 2. When the pressure on the key is released the spring G contracts and the typehar and key-lever return to their normal positions. There are several important advantages in this arrangement, one is the absence of mechanism between the key-lever and the type-bar, another is that the key-lever can be made very short and simple in construction,

spring is small and the spring can therefore be made comparatively stron .1

Various devices ma be use for maintaining the alinement o the parts. Thus the block C may be extended to form a comb which engages the lower part of all the type bars D an prevents lateral play thereof. The usual guides may e provided immediately above ,the platen B. Each type bar D has a cam portion D at its lower end arranged to engage a universal bar H mounted beneath the t pe bars.

The metho of mounti is illustrated in Fig. 4.

the universal bar ne arm H is pivthe right-hand side of the universal bar. The frame H is pivoted to the' right-hand side of the base and carries an arm H pivoted to the left-hand side of the universal bar and the bar H is pivoted to the frame H". The bar 11 is slotted at its left-hand pivot where it is attached to the base A and the arm H is slotted at the ivot where it is attached to the left-hand si e of the universal bar to give the'pivots a certain amount of piay. A strip H proiects from the frame The depression 0 the universal bar H operates an esca ement for the platen earriage in any usua way. For example it may carry a fixed tooth J and a spri g-controlled tooth J one above the other, arran ed to en gage alternately with the rack B o' the carria e so that'as the universal bar H moves up an down the esca ement of the carriage 1S operated in a well own way. The space key K carried by a plivoted frame K has a projection K centre ed by a spring K and arranged to engage the, stripfH and actuate theescaperne'nt. v The method lby which theupper'fr'ai'neC is mounted on the base A will 'e'" clear from Figs. 1, 2, 3 and 5; the upper frame G to removedtog'ether with the type-bars and key-levers. A carrier L having vertical arms L at its ends is pivoted to the mainframeA at L and the arms L have slotsL'. in their 11 per ends. Idler arms M one on each side 0 the machine are as to the base A and also have slots M intheir and a third is that the total extension of the oted to the left-hand side of the frame and to The obj dot is to enable. be readily'and entirely attached in like manner 'be the same.

upper ends. .The links M one at each side connect L and M and hold them in such relation to eaehother as to permit the four ins N projecting from the block C to engage our s ring arms 0 pivoted at O and havin suita le holes to engage the pins N. pring washersO hhld the arms 0 normally in posiarms 0 outward tion. By pressing the four they are released from the pins N and the whole upper part of the mac iine is then free to be removed.

It is desirable that the depression rer uired for all the key-levers in the machine s ould It will be appreciated that owing to the different lengths of the keylevers in the different rows, special means. have to be provided to insure this. In the resent construction equal depression of the ey-levers is obtained by varying the inclination of the approximately vertical slots F; thus in the to row of key-levers the slot F may be slight y inclined'downward and forward. In the key-levers of the middle row the slot F can be made vertical and in the ke levers of the bottom row the slot F ma e slightly inclined downward and bac ward.

The method of shifting from one set of characters to another is shown in Figs. 3 and 11. A shift-key P is pivoted to a link P fixed to one of the arms M and the shift-kc has a central finger P rojectin downwar The shift-kc is norma ly in its ighest position in whic case the t pes d are in operative osition. When t e front portion of the s iftekey is pressed-downward the finger P e ages a stop Q on the'base and the u per sli ing' frame is pulled forward sufficiently to bring the center types (1 into operative osition. When, on the other hand the ack portion of the shift-key is pushed down, the finger P does not engagg the stop Q but the link P engages a stop and brings the uppermost set of types cl into operative position.

' In Figs. 9 and 10 which illustrate a modified arrangement of the space-bar, the spacebar S is supported on a spring-controlled lever pivoted at the center of the slidin frame C and arranged to engage a strip I 4 pfoggpting from the frame H.
